The article discusses how using solar technology called BIPV/T systems in buildings can help achieve energy efficiency goals and cut down on harmful emissions. These systems generate both electricity and heat while making buildings look good. The research looks at ways to model and simulate how well these systems work in different conditions. Scientists have been studying how these systems can help make buildings produce as much energy as they use and reduce their carbon footprints to zero. The study reviews several projects showing that BIPV/T systems can be a key player in reaching these sustainability goals. The researchers suggest further areas for study and experimentation to keep improving this technology.
